Overall Dual-stack

Collected2026-10-14 16:33 UTC

Measurement estimates from a single vantage point — not a compliance certification. Guidance below is for operators, not an SLA.

Priority next steps

Enable DNSSEC signing and publish a DNSKEY at the apex. Use DNSViz to validate the full chain.
Publish a _dmarc TXT record (start with p=none, then tighten). Check policy on dmarcian.

Checks

DNS

Dual-stack

[2] 2/2/2 [O]

Meaning: Shows how many authoritative name servers exist, and how many IPv6 endpoints are configured, responsive, and operational.

IPv4 2/2/2 · IPv6 2/2/2 · location O

Host	IPv4	IPv6	Probes
`dns100.ovh.net` [O]	5.135.250.177	2001:41d0:d00:fa00::2	ipv4 5.135.250.177 ok; ipv6 2001:41d0:d00:fa00::2 ok;
`ns100.ovh.net` [O]	5.135.44.185	2001:41d0:b00:f400::2	ipv4 5.135.44.185 ok; ipv6 2001:41d0:b00:f400::2 ok;

Mail

Dual-stack

[1 MX] v4 smtp 4/4/4 v6 smtp 4/4/4 [O]

Meaning: Shows MX footprint and SMTP health per IP family. Operational means an SMTP banner and EHLO exchange succeeded on port 25.

IPv4 SMTP 4/4/4 · IPv6 4/4/4 · location O

Host	IPv4	IPv6	Probes
`saintbarthtourisme-com02e.mail.protection.outlook.com` [O]	52.101.41.125, 52.101.8.5, 52.101.9.24, 52.101.60.188	2a01:111:f403:c918::5, 2a01:111:f403:f909::5, 2a01:111:f403:c922::7, 2a01:111:f403:f804::	ipv4 52.101.41.125 ok; ipv4 52.101.8.5 ok; ipv4 52.101.9.24 ok; ipv4 52.101.60.188 ok; ipv6 2a01:111:f403:c918::5 ok; ipv6 2a01:111:f403:f909::5 ok; ipv6 2a01:111:f403:c922::7 ok; ipv6 2a01:111:f403:f804:: ok;

Web

Dual-stack

[1] 1/1/1 [I]

Meaning: Shows IPv6 web endpoint readiness for the discovered HTTPS host. Operational means family-specific HTTPS requests complete successfully.

IPv4 1/1/1 · IPv6 1/1/1 · location I

Host	IPv4	IPv6	Probes
`www.saintbarth-tourisme.com` [I]	198.202.211.1	2620:cb:2000::1	ipv4 ok; ipv6 ok;

DNSSEC

Unsigned

U/-/-

Meaning: Shows whether DNSKEY data is observed at the apex (signed), absent (unsigned), or unavailable due to lookup error.

Apex DNSKEY presence only — not full chain validation.

Analyze on DNSViz

📌 Action item(s):

Enable DNSSEC signing and publish a DNSKEY at the apex. Use DNSViz to validate the full chain.

DMARC

No record

No record — no TXT at _dmarc.saintbarth-tourisme.com.

Meaning: Published DMARC policy at _dmarc.saintbarth-tourisme.com (DNS TXT). Shows organizational policy (p=) and subdomain policy (sp=) when set.

Publish a DMARC TXT at _dmarc.saintbarth-tourisme.com (often start with p=none, then tighten).

Policy publication only — SPF/DKIM not measured. Not part of the 0–4 row score.

Check on dmarcian

📌 Action item(s):

Publish a _dmarc TXT record (start with p=none, then tighten). Check policy on dmarcian.
